What is the correct post-production order for AI-generated video — upscaling, color grading, and film grain?

The correct order for AI-generated video is: upscale first on the raw ungraded footage, then color correct to a neutral baseline, then apply your color grade, and add slight blur and film grain last. Upscalers read raw pixel data, so they perform best before any color transform — and grain must never be baked into the grade.

Run the four steps in this sequence, and run them on every AI-generated clip — AI footage needs this chain more than live-action does because models render below delivery resolution and produce an over-sharp, synthetic surface texture that only post-processing removes.

1. Upscale first, on the ungraded clips. Upscaling algorithms work on raw pixel data, so feed them the neutral image straight out of the model — grading before upscaling introduces color-space shifts the upscaler can misinterpret. invideo is an agentic video creation tool with the current models and upscalers available in one place: Topaz Astra runs on invideo and is the documented first step of the AI film post-production pipeline, applied before any color work. To batch the step, spin up a sub-agent inside the invideo agent named for the job — an upscale artist — and it processes footage without per-clip manual intervention.

2. Color correct to a neutral baseline. Correction is the technical pass, not the aesthetic one: balance exposure and white point and match clips to each other so every shot starts from the same neutral image. Skipping this means your grade fights shot-to-shot inconsistency instead of building a look.

3. Apply the color grade. This is where stylistic intent goes — palette, contrast curve, mood. The invideo agent carries a documented 8-step color grading guidance process, so you can ask it for grade direction against your visual references rather than dialing the look in blind.

4. Add blur and film grain last. Slight blur plus grain is the specific fix for the known artifact of AI generation: heavy Seedance 2.0 output shows an ultra-sharp, plasticky skin quality that reads as synthetic. invideo's creative team describes the finishing move directly: a tiny amount of blur over the scene, a layer of grain, then refining the grade until it sits close to live-action film. Grain renders at the end of the chain so it is never baked into the grade and so it masks any remaining processing artifacts — which is also the practitioner consensus order in traditional grading workflows. One documented production ran this exact pipeline as proof it scales: a four-person team finished a short film with international locations and VFX in roughly 4 days for ~$5,000 (20,000 credits), applying upscale-then-color-then-grain to every generated clip before final assembly in their edit suite.

Watch some of these to see what works for you:

What we tend to do is put a tiny bit of blur on top of the scene, add a bunch of grain and then play with the grade till it comes closer to live action film.
